Polyvinyl fluoride

Polyvinyl fluoride (PVF) or –(CH₂CHF)_n– is a polymer material mainly used in the flammability-lowering coatings of airplane interiors and photovoltaic module backsheets. It is also used in raincoats and metal sheeting. Polyvinyl fluoride is a thermoplasticfluoropolymer with a repeating vinyl fluoride unit, and it is structurally very similar to polyvinyl chloride.
